Subject: [ARM] Restrict {load,store}_multiple expanders to MAX_LD_STM_OPS regs
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f5ee50a5ab6e5211632d7e5dd6c977d715e6f3b6;p=gcc.git

[ARM] Restrict {load,store}_multiple expanders to MAX_LD_STM_OPS regs

	* config/arm/arm.md (load_multiple): Reject operand 2 greater than
	MAX_LDM_STM_OPS.
	(store_multiple): Likewise.
